CAN-SALTING MAoHlNE.

Specification of Letters Patent.

Patented may ai, 1907.

Application filed March 1,1905. Renewed April 8, 1907. Serial No. 367,107.

ing a citizen of the United States of America,"

residing at Bellingham,- in the county of Whatcom and State of Washington, have invented certain new and useful Improvements in Can-Salting'Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in salting machines of that type designed lto deposit measured quantities of salt into cans prior to the packing thereof, and the primary object thereof is the production of a simplified and improved construction in which the waste of salt is reduced to a minimum.

Further objects and advantages will be set forth in the following description and those features of construction upon which I desire patent protection, defined in the appended claims.

In the accompanying drawings in which like ,numerals of reference indicate like parts throughout the several views: Figure 1 is a plan view ,of my improved machine showing the cam for operating the ejectors mounted. on the salt carrier in partial section taken on line 1 of Fig. 9. Fig. 2 is a similar view of the machine in horizontal section 'taken on line 2 2 of Fig. 3 with the salt receptacle and the chute removed and shows a can being fed, the same having effected the wit h drawal of the supplemental track section of the cam. Fig. 3 1s an end elevation of the machine shown in partial section taken through the salt carrier and adjacent parts.

' Figs. 4 and 5 are detail views of the rotary of said ejectors being shown engaging saidl y o section. Fig; 1) 1s a sectiontakenbn line ]()-10 of Fig. 9, and Figs. 11 and 12 are detail views of the supplemental track section of the cam and the means for movably supportingthe same.

' In carrying out my invention I providea suitable frame including a base 1, supported on a pedestal 2 and having a stand 3 secured to the u per face thereof adjacent one corner.

4 in icates the drive shaft journaled in suitable hanger brackets 5 secured to the rear end of said bar and on this shaft a .suitable drive pulley as 6 and a driven pulley 7 are secured. p

Supported on the stand 3 is a salt receptacle 8, the bottom of which is formed with a discharge opening and curvedv inwardly on an arc of a circle, and the side walls of said re-` ceptacle are curved inwardly Aso as to resent opposing curved inclined faces ten ing directly to said discharge opening.

9 indicates a salt carrier which forms a closure for said discharge opening, the rim thereof extending thereacross and having its edges snugly engaging in grooves 10 extending along the side edges of said opening. The rim`of this carrier has secured to one edge, the arms of a spider 11, which is fixed on a shaft 12 journaled in the stand 3 and projecting through a cam section 13 formed integral with the inner face of 'said stand. 14 indicates pockets formed in said rim and in these pockets ejectors 15 operate, the latter being in the form'of plungers having angularly ydisposed stems 16 pivoted intermediate their ends as at 16 between the arms of said spiders and having their free ends provided with rollers 17 arranged in the groove of cam 13. These plungers therefore form bottomsy for the pockets 14 and as they have an arc like movement, by reason of -the pivotal connection of their stems, I curve the side walls of said pockets accordingly. l

The salt receptacle is preferably formed in two vertical sections, asshown, and at the contiguous edges thereof I provide the half bearings 18, ywhich when the two sections are bolted together form bearings for the agitator shaft 1 9. This shaft'occupies an inclined packing of the salt about the rim'of the salt carrier. The outer fingers are of greater position and is provided with end and intermediate 'lingers 2O which serve to preventV IOC length than the intermediate ones and as shown in Fig. 8, have movement into the narrow spaces between the rim ofthe salt carrier and the forward and rear walls of the salt receptacle. On the upper end of this sh'aft 19 I provide the bevel gear 21 which meshes with a similar gear fixed on the shaft 22, the latter being journaled in an elongated bearing 23 secured to said stand. Asprocket wheel 24 is mounted on the outer end of this .shaft and similar wheels, as 25 and 26 are provided on the shafts 4 and 12 respectively and a sprocket chain 27 .passes over the gears,

24 and 25 and has the forward run thereof engaging sprocket wheel 26. By this construction, power'being applied to. the drive shaft 4, by eans of a belt (not shown) pass'- ing over pu ey 6, movement of this shaft will be transmitted to the shafts 12 and 22, thereby simultaneously rotating the agitator in the salt receptacle an'd the salt carrier. As the salt carrier is revolved the rollers of the stems 16 'are moved around in the groove of the cam, which being: irregular in formation serve to raise and lower the plungers 15. The cam groove is so shaped that the-respective rollers will engage the part a,v thereof when the pockets come to their upper position, so that the plungers 15 are lowered and salt thereby allowed to drop into the pockets. When the rollers reach the point b of the track they are raised so as to move the plungers through their pockets to eject the salt therefrom.

28 indicates an adjustable cam section (see Figs. 6-7--9 and 10)'whichis formed with the flanges 28a and 28by forming continuations of similar flanges of the stationary cam section 13, and as this section 28 is adjusted in its guideway 29, formed on the stand 3, to andfrom the center of' the cam, the outward lmovement of the rollers when engaging between said flanges 28a and .28? will-obviously be varied and consequently a greater or lessy degree ol' movement, as the case may be, will be imparted to the plungers 15 so that the capacity of the pockets is varied. This cam section 28 is held in lits adjusted position by means of bolts 30 which pass through slots in the wall of the guide way 29 (see Fig. 9.).

By reference to Fig. 8 of the drawing it will be observed that although the.pockets are filled with salt when they reach their upper position, yet they are still kept in communication with the supply until they pass the scraper plate 31. The' object of this is that should there be an interruption inthe con;

tinuous feeding'of the cans, for instance one.

or more cans being omitted from a line ofl cans fed to be salted,the salt in those pockets, which would have been deposited in said cans, may be forced back into the salt receptacle at the pointe of rotation of the carrier,

and ,therefore the loss of salt which would otherwise haveI occurred, vis prevented. Thel mechanism for operating the plunger at this point- (c) of rotation of the carrier consists-of a supplemental track section 32 which is movable through a slot 33 formed in the cam section 13 and back wall of guide way 29, over a ortion of the outer flange of the cam which 1s supplemented thereby. This track section 32 is rigidly affixed to a horizontally disposed L-shaped extension 34 rof the vertical arm 35, th1s latter arm being also rigidly secured to the free end of) the swing arm 36 pivoted at 37 at one side f and adjacent thc forward end of the machine. This arm 36 is also formed at its free portion with a hori- -Zontal branch' arm 38 the free end of which extends over the active run of 'a conveyer belt 39 and is provided with a roller 40 which is adjustably mounted in the slot 41 of the arm 38. The swing arm is pressed toward the conveyer belt by a spring 42 so that the supplemental track section is normally dise posed inthe cam over a portion of its outer Harige.

The b'elt 39 extends longitudinally of the base ,with the activefrun lthereof overlying the upper face of the base, and passes over, driven pulley 7 and a suitable idler pulley (not shown) disposed at a convenient distance from the machine.

43 indicates a link belt conveyer arranged on the upper face of the .base and passing over an idler 44 and a driven sprocket wheel 45 which is mounted on a vertical shaft to which, movement is transmitted from the drive shaft 4 through gears 46 and 47. This conveyer is `provided with spaced apart ,plates 48 and is arranged with its active runs angularly disposed to the conveyer belt 39, the same extending toward said conveyer belt in a forward direction relatively to its travel. Extending along the rear side of the active run of the conveyer 43 is a backing plate 43', which is suitably mounted on base 1 and holds the conveyer from sagging.

49 and 50 indicate guides which lie on opposite sides of conveyer 39, the former being pivoted at 51 and having ,its forward end yieldingly heldl by spring 52, and the latter guide being rigidly held upon the base beneath the path of travel of ythe plates 48. The guide 50 is adjustably mounted, a pre- TIO ferred means for accomplishing the result being-shown, the same consisting in providing said guide with outwardly projectin slotted ears 5 3 through the slots of whichgbolts 54 project. y

55 indicates a c'hute which is secured to the stand 3 and receives the lower portion of the salt carrier 9 so as to prevent any loss of salt from the pockets and insure of the same being properly deposited in the cans.

n operation the cans to be salted are placed on the conveyer belt 39 and thus fed between the guides 49 and 50 at which point they are engagedl by the plates 48 a 1 parent thatv in the event of the salt not being firmly packed in a pocket entering the chute 55, that falling saltA therefrom will be caught by the inclined side wall of said chute and directed thereby to the can which is then moving beneath the chute. During the movement of the cans thus far referred to, each 4 can engages roller 40 thereby swinging arms 35-and 36 outward and as the cam track section is rigidly secured to the extension 34 of arm 35 it will be moved through slot 33 to the rear of cam section 13 and thus the plungers will not be operated until the rollers of their stems reach point b in their path of travel. If there failshowever,` to be a can between any of the plates 48 the roller will obviously not be operated when said plates pass, and the supplemental track section 32 will therefore not be moved from engagement with the outer Harige of the cam. Therefore when the roller on the stem 16 of the approaching. plunger l5 engages said supplemental track section it causes said stem to move the plunger outward and eject the salt from the pocket back into the salt receptaclc at the point marked c. When the cans are lsalted they are conveyed down a suitable discharge chute 56 at the rear of the machine, a guide 56 being mounted on base 1 opposite to the rear portion of guide 50 to guide the cans as they pass from roller 40.

It will be observed that by providing a yielding guide opposite the conveyer43, that the cans will be prevented from being jammed by the plates 48, should the cans not be properly presented for said plates to move freely between them.

The guide 50 being adjustable it can be readily set so that the cans will be accurately fed relatively to the roller 40 to shift the supplemental track section clear of the path of travel of cam rollers.

In the present showing I have illustrated a convenient form of t-ightener for sprocket chain 27, the same embodying the sprocket wheel 57 engaging said chain at a convenient point and being mounted on a bracket 58 adjustably secured to stand 3.
